I bought some replacement channel balances (ordered the S395).
The problem I have after installing the new channel balances and sash guides is firstly, the window is difficult to lift and to pull down, but more importantly, the window will only go half way down and I can't figure out what is preventing it from closing. I have taken the window out and reinstalled it several times to no avail. The only markings on the old balances were, 29-6 CA2 CMC 4. I wasn't sure if this designated weight so I removed the window and weighed it before ordering. The weight was 32 lbs. so I believe I ordered the proper balances(option 2960).
I would appreciate any help you may be able to give me.
